HunanContainerwhich is placed at the edge of the carriage to ensure a smooth transition between the passage and the carriage. Its advantages are as follows.
Install drainage ditches on the ground near the pit of the simple boarding bridge, and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
Hunan.Features: Generally, domestic brands are the main products with a lightweight boom design, which has a wide range of operations, lightweight flexibility and high work efficiency. Large leg span, good stability, automatic detection of leg reverse force, stop getting on if any leg loosens. When the chassis power system malfunctions, ensure that the platform car can be lowered and the rotating mechanism can be manually rotated. The cylinder rod is protected by a protective sheath, and the arm head is equipped with a dustproof device.
Install drainage ditches on the ground near the pit of the simple boarding bridge, and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
.The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
For slopes that are unstable or unstable after earthwork excavation, top-down segmented trench jumping should be adopted based on the geological characteristics and possible situations of the slope, and reverse construction or partial reverse construction should be carried out in a timely manner. It is strictly prohibited to excavate and explode indiscriminately.
Shake the handle to raise the boarding bridge to the height of the container.
When working in foundation pits or depths, a helmet must be worn.
On a moving steel structure slope,HunanMobile boarding bridge, forklifts can also directly enter the interior of truck carriages for bulk loading and unloading operations. Fast loading and unloading of goods can be achieved with only one person operating and without the need for power supply.
What should I pay attention to when choosing a boarding bridge? The selection and purchase of the boarding bridge involves paying attention to three issues, including its range of use, rated load, and other factors; Their understanding of the manufacturer of the boarding bridge,HunanMaintenance of boarding bridge, special equipment licenses are complete, how many after-sales service outlets are there in the country, how about their after-sales service attitude and whether they are timely; The important point is whether the quality is good or not, and whether the price is reasonable. If both of these situations are reasonable, you can choose the products of the manufacturer.
Bidding.Slowly reverse and park the container under the lip at the front of the boarding bridge.
Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating, motor reverse, motor phase loss (motor not moving and buzzing), indicator light on, lowering valve is open, overflow valve pressure is low, oil level is too low, oil pump is empty, oil suction filter is blocked, oil suction section is leaking,HunanProduction of boarding bridges, and two phases in the three-phase line are arbitrarily changed; Solution: Check the starter potential during motor load operation. Voltage hydraulic range allowed± １０％； Check the motor and circuit; Check the circuit breaker and motor wiring; When the lowering button is released, use a voltmeter to check whether the lowering valve is energized. If there is no power, check the circuit and eliminate the fault; If there is electricity, eliminate the malfunction of the lowering valve itself. The slide valve of the lowering valve must be kept clean and move flexibly. Readjust the overflow valve. Adjust at 100% rated load; Fill up the hydraulic oil; Clean the filter; Check the oil suction pipe and joints; Tighten the joint and replace it if necessary.
Reason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.
During the excavation process of the foundation pit of the simple boarding bridge, collision of the support structure should be prevented, and changes in the soil wall should be paid attention to at all times. If any abnormal phenomena such as cracks are found, construction must be suspended and reported to the superior for handling.
Quality assurance.Slowly reverse and park the container under the lip at the front of the boarding bridge.
Applicable scenario: Suitable for mobile high-altitude operations such as setting and inspection of high-altitude equipment in various industries.
When working on the hydraulic boarding bridge, the support legs must be extended, and the support leg bolts must be adjusted to ensure that the lifting platform is stably stressed on the support legs and kept horizontal; During the lifting process and in the lifting state, the lifting platform must not be moved, and it is strictly prohibited to shake on the lifting platform. If there is an abnormal sound during the operation of the hydraulic boarding bridge, it should be stopped immediately for inspection to avoid causing serious damage to the lifting platform; Before use, check whether the electrical equipment is normal; All shaft pin oil holes must be oiled before each use. Before use, it is necessary to perform no-load lifting and check whether the hydraulic system is normal; The load of the workbench should not exceed the rated value, and it should not be subjected to intense manual shaking; The hydraulic oil in the oil tank must be replaced every 500 hours of operation.
Hunan.Connection for. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations.
The safety valve of the mobile hydraulic boarding bridge can also generate high noise. When air is mixed into hydraulic oil, the relief valve gets stuck or severely worn and the fatigue deformation of the relief valve spring leads to unstable pressure regulation of the relief valve. The pressure release time of the relief valve is too short, which can easily lead to local stability of the pilot valve performance of the relief valve. Noise is generated by the vibration of the pilot valve's air. Therefore, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.
These are the options for hydraulic oil for mobile boarding bridges.
